"This lens looks ordinary, as if it has some hexagonal honeycomb grille on the lens. But in reality, these honeycomb grilles are not on the surface, but inside the lenses.

If it is just a hexagonal honeycomb grille, it will not change the light transmission of the lenses or each hexagonal honeycomb.

Our lens, on the other hand, can change the light transmittance of each hexagonal honeycomb grille. ”

As he spoke, Wu Hao turned the lens, and a beam of light shot towards the lens, and after passing through the lens, it hit a blank piece of paper. I saw that many ultra-bright spots of different sizes appeared on this white paper.

"Because each hexagonal grid lens has a different focal length, these concentrated light spots naturally have different sizes.

This is very important, everyone should remember, especially future consumers, pay attention to observation, do not be deceived by copycat products. ”

Wu Hao smiled, and then continued: "What about such a lens, if it is manufactured according to normal methods, it will be very difficult. This means that we need to machine different bumps on the surface of a large lens. ”

While Wu Hao was speaking, the screen was also showing the style of the lens in which Wu Hao spoke.

"The lenses that come out like this are very difficult to process, very expensive to manufacture, and the yield rate is very low.

So in the end, after our repeated research, we changed the way we thought about the manufacture of this hexagonal honeycomb lens. We decided to abandon this traditional way of processing lenses and instead use a new set of technologies developed by our crops.

Through laser printing or laser engraving technology, the outline of a hexagonal honeycomb lens is engraved or printed in a high-lens lens made of special materials.

And this is only the first step, although the contour of the lens has already appeared, it is affected by the structure of other superfluous lenses, and the optical refraction phenomenon cannot be generated.

Therefore, at this time, we need to make special treatment for the lens material of other parts of the hexagonal honeycomb lens lens to make it lose the glass refraction phenomenon.

In other words, optics do not refract when passing through the glass. In this way, the lens that is carved into the inside of the lens works. ”

Genius idea!

The audience who was watching the live broadcast of the new technology promotion conference couldn't help but admire, and countless people in the industry couldn't help but smile bitterly.

The technique sounds easy, and it seems like the principle is very simple, but why hasn't anyone done it before?

Craft, what Wu Hao deliberately ignored in his preaching.

What lens material, I don't know. It is also not known what laser printing and engraving technology will be used. It is not known how to eliminate the light transmission refraction of the excess lens.

This is the biggest difficulty of this technology.

After taking a sip of water, Wu Hao continued: "Now, this hexagonal honeycomb lens has been successfully manufactured, so can it produce lenses?" ”

Wu Hao shook his head and said, "There are still many problems,

The first problem is how to reflect the focal points of these large and small hexagonal honeycomb lenses onto a photosensitive component.

These hexagonal honeycomb lenses are of different sizes and thicknesses, so the length of the focal points is naturally different, and how to concentrate these focal points on a single sensor is a tricky problem. ”

After throwing this question, Wu Hao paused for a moment, and then replied: "Mirror, lens!" ”

"We used the principle of mirror reflection and lens refraction in tandem to finally align the focus of these hexagonal honeycomb lenses on the photosensitive components.

And by adjusting the angles of these mirrors and lenses, we can change the focal length of these lenses and thus make zoom adjustments. ”

As he spoke, this hexagonal honeycomb compound lens appeared in front of Wu Hao. The entire shot is suspended in the air and slowly rotates.

Syllable!

Wu Hao snapped his fingers, and this hexagonal honeycomb compound lens actually disintegrated in the air.

Stretching the lens, the audience can more intuitively see the complex structure inside this hexagonal honeycomb compound lens lens.

As he spoke, Wu Hao tapped a little with his finger, and a beam of light came directly, and the light passed through various lenses, and then gathered on the surface of the image sensor.

"With this manufacturing process, we can process multiple layers of lenses on a single lens, which can theoretically be infinite, depending on the thickness of the lens material.

We can even carve numerous lenses and mirrors into a lens material or a lens material.

Light is constantly refracted and reflected through these lenses and mirrors, and finally the corresponding optical effect is achieved. ”

So what is the use of this compound lens technology made in this way?

After throwing this question, Wu Hao did not answer in a hurry, but gave the audience watching the live broadcast some time to think.

After waiting for about ten seconds, Wu Hao slowly replied with an affirmative tone: "The effect is very big, even greater than you all imagined."

With this compound lens technology, it is not only possible to make our hexagonal honeycomb compound lenses, but also to create light from them.

That's right, make light!

What comes to mind? ”

"Lasers, the most powerful artificial light source we humans make. Our composite lens is an ideal laser light source lens.

We've done tests where lasers using our composite lens technology deliver more than 50 percent more power than lasers using conventional lenses at the same power source, and we think there's a lot of room for improvement.

I'm sure you all know what this means and how it will change our industrial production and processing and other applications. ”

After throwing out such an amazing result, Wu Hao did not pause, but continued to raise his tone and speak.

And I would say that that's not all, with this composite lens technology, we can use it to make extreme ultraviolet light sources.

Theoretically, using this technology, we can directly compress the EUV light source to the current level of the current international cutting-edge EUV light source, or even better than it!

What the!

At this moment, many people stood up directly.

How is this possible?

The audience exclaimed, you must know that the extreme ultraviolet light source is the core technology of the lithography machine. Once this technology is overcome, then the lithography machine is not a problem at all.

Now, Wu Hao and the others actually claim that they can create an extreme ultraviolet light source of the international cutting-edge level, how is this possible, I'm afraid it's bragging.

Don't believe it, don't believe it. This is the first reaction of countless people after hearing the news.
